Match List I and II and select the correct answer with the help of the codes given below the lists
`{:("List I","List II"),("A. Somatotropin","1. Neurophypophysis"),("B. Oxytocin","2. Cretinism"),("C. Thyroxine","3. Rickets"),("D. Vitamin D","4. Gigantism"):}`

Options

A. A = 3, B = 1, C = 4, D = 2
B. A = 4, B = 1, C = 2, D = 3
C. A = 2, B = 3, C = 4, D = 1
D. A = 1, B = 4, C = 3, D = 2

Answer

To solve the problem of matching the items in List I with those in List II, we will analyze each hormone and its corresponding condition or description step by step.

### Step-by-Step Solution:

1. **Identify Hormone A: Somatotropin (Growth Hormone)**
- Somatotropin is produced by the pituitary gland.
- Excess secretion leads to **Gigantism**, while insufficient secretion can lead to dwarfism.
- **Match:** A → 4 (Gigantism)

2. **Identify Hormone B: Oxytocin**
- Oxytocin is also produced by the pituitary gland, specifically from the neurohypophysis.
- It is primarily involved in childbirth, stimulating uterine contractions.
- **Match:** B → 1 (Neurohypophysis)

3. **Identify Hormone C: Thyroxine**
- Thyroxine (T4) is produced by the thyroid gland and regulates metabolism.
- Insufficient levels during development can lead to **Cretinism**, characterized by stunted growth and developmental issues.
- **Match:** C → 2 (Cretinism)

4. **Identify Hormone D: Vitamin D**
- Vitamin D is crucial for calcium metabolism and bone health.
- A deficiency in Vitamin D can lead to **Rickets**, a condition affecting bone development in children.
- **Match:** D → 3 (Rickets)

### Final Matches:
- A → 4 (Gigantism)
- B → 1 (Neurohypophysis)
- C → 2 (Cretinism)
- D → 3 (Rickets)

### Correct Answer Code:
The correct answer code based on the matches is **2**.
